So this was something I heard from a friend of a friend type thing. Anyways this guy was engineering for Ryan Adams a few years ago and Ryan told him to put a really small delay on his vocals - so small that you can't exactly hear it delay. But apparently Adams has been using this for years to get his vocals to sound really wide and full. I can't remember the full details of the delay setting, just make the time really low and I'm guessing feedback really high. Anybody heard of this before?
